Overview

CVE-2010-4530 is a medium-severity vulnerability affecting muscle pcsc-lite. It was published on January 18, 2011 and has a CVSS 2.0 base score of 4.4 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.4, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

Signedness error in ccid_serial.c in libccid in the USB Chip/Smart Card Interface Devices (CCID) driver, as used in pcscd in PCSC-Lite 1.5.3 and possibly other products, allows physically proximate attackers to execute arbitrary code via a smart card with a crafted serial number that causes a negative value to be used in a memcpy operation, which triggers a buffer overflow. NOTE: some sources refer to this issue as an integer overflow.

Remediation

Check the references section for vendor advisories and patches from muscle. Update pcsc-lite to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
